Prostaglandi analogues were used to induce luteal regression simutaneously in a number of ewes, thereby synchronizing the final stages of follicular maturation in these animals. Some of the ewes were anaesthetized for 24 h immediately after the injection of prostaglandin (experiment 1), and others for 15 h, starting 24 h after the injection of prostaglandin (experiment 2). In both experiments administration of anaesthetic significantly delayed the onset of oestrus and the time of ovulation relative to prostaglandin-treated control animals. The results from assays of blood samples collected at regular intervals in experiment 1 indicated that the preovulatory peak in the concentration of LH and the periovulatory changes in the concentration of FSH were similarlydelayed and that during anaesthesia the level of LH was significantly reduced. It is suggested that the reduced level of LH, which probably resulted from a reduction in the secretion of releasing factor due to anaesthesia, failed to support oestrogen production by the Graafian follicle(s), thereby delaying the occurrence of oestrus and ovulation. |
